LUBRICATOR.

SPECIFICATION forming'part of Letters Patent No. 414,599, dated November5, 1889.

Application filed May 29, 1889. Serial No. 312,597Y (No model.)

To all wiz-0712, it may concern.-

Be it known that I, MAURICE SPITZER, a native of Austria-Hungary, butwho has made application to become a citizen of the United States, aresident of Dayton, in `the county of Montgomery, in the State of Ohio,have invented a certain new and useful Improvement the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this speciication.

My invention relates to that class of lubricators in which the lubricantis fed drop by drop to the steam-chamber, where it lubricates thevalves. It is also provided with windows for observing the feed `andmeans for operating and regulating it.

The details of my invention will be more fully hereinafter set forth.

In the accompanying drawings, Figure lis a vertical section of myimproved lubricator; Fig. 2, a side elevation, partly in section; Fig.3, a horizontal section through the line so, Fig. l.

Like letters of reference indicate identical parts in the differentfigures.

The main body of the lubricator consists of a circular cup, which holdsthe lubricant. The inner metal walls A A of this cup are provided withopenings B B, and the whole is surrounded with a glass jacket or casingO, perf mitting the contents of the cup to be seen.v From the bottom Aof this cup there extend the converging flanges or sides D D, ending ina vertical tube or pipe D'. These converging walls D D form a secondchamber E below the oilcup A, which opens directly into the steam-pipeD'. The interior of this chamber E is made visible by the windows F. Onthe top of the cup A is fastened the domeshaped cap G, fastened to thecup Aby screwthreads, as seen at a. This dome-shaped cap G provides adome-shaped chamber G beneath or within it and above the open top of thecup A;

H is a wooden zone around the oil-cup, by

is used to provide a cool surface for the hand, as the cup itselfbecomes quite hot.

As it is undesirable to have water in the steam-chest, that which flowsthereinto from the lubricator is removed through the usual petcock.

One of the advantages which results from vmy construction of lubricatoris that the 11ecessity for an additional cock or opening on thelubricator is obviated.

At the lower end of the pipe D is provided a valve constructed asfollows: A tubular casting I is provided to embrace the lower end of thetube D' and enlarged around the open ing of the pipe or tube D', as atI'. Inside of this enlargement is a seat J.n The lower end of the tube Dis made in two pieces to permit the adjustment of the stuffing-box K,the

lower piece D" being screwed into the lower end of D', as seen at d,after the stuffing-box K has been put into place. On the outside of thelower end of the pipe D D are large screw-threads L, corresponding withsimilar threads on the inside of the casting I. The lower end of thetube D" rests upon the seat J. 7c 7c are ports formed in the inside ofthe casting I and opening above the seat J, and affording directcommunication from the opening M in the casting I to the pipe D' whenthe pipe D' is lifted from the seat J.

k is a washer to form a tight j oint.

The casting I is screwed directly into the steam-chest by thescrew-threads around the outside of its lower end, and steam isdischarged through the opening lll and ports 7n.

The casting I is stationary, so that when the cup or lubricator isturned slightly the screw-threads L lift it, raising the lower end ofthe tube D" from the seat J and opening the ports lo k into the tube D'.

Through the center of the cup A is the vertical pipe N, open at bothends, the lower end opening into the chamber E and the upper into thechamber G above the oil-cup. Near the upper end of the pipe N is adip-pipe N', bending downward into the oil-cup A. In the bottom of theoil-cup A is a valve P, provided with a stein P', extending up into thechamber G'. This valve is provided with a collar at any convenientpoint, as at P", into which it is screw-threaded, s0 that it can beopened or closed byturning in its collar. For convenience the cap orcovering G is provided wit-h an opening covered with the cap O, which isscrewed down perfectly tight. This cap O is also provided with an armO', extending down into the chamber G', Whose lower end is formedinto aWrench, whichl can be used when the cap O is lifted to turn thevalvestem P.

The operation is as' follows: The casting I being screwed firmly intothe steam-chamber, Where it remains stationary, the 'cup A isi lled withoil and closed up tight. The lubricator-is then turned slightly by thehandle or zone II and the lower end of the pipe D lifted from the seatJ, opening the port lo and permittingthe steam to enter. lThis steamfillsr the chamber E and passes up through the pipe N, through theshaft-tube N2, into the chamber G. Some of it may be condensed inthechamberE. lVloreis-condensedinthe chamber G. The water thus formedfalls to the bottom of the cup A, causing. the oiltorise and' viiowthrough the dip-pipe N .and'pipe N. The lower endA of the pipe'N isprovided-'with a wire cage to cause the oil tovadhereuntil? a Vlargedrop is formed, as seen at y. The oil thence drops'through-the-tube or.pipe: D and' passes through the open ports k into the'stealnchest,-Where it lubricates the parts. Theflow of the lubricant can beregulated by the turning of the lubricator and: increasing' .ordiminishing the openings in the ports k. :Its operation can be observedthrough the windows Gand F. When water accumulates from condensationlinthe cup AI discharge it back into the steam-chest instead of outside.This is done by closing t-he portsk, taking off the cap O, and openingthe valve P, through which the Water passes to the chamber E. The valveP is closed. The cup is then filled with oil, the capi() replaced, andthe ports 7c opened, and the-Water flows through them into thesteam-chest.

Having thus fully described my invention what I claim,and desire tosecure'byiLetters 1. In a lubricator in which the lubricant isdischarged by Water of condensation, an oilchamber having a tube N,provided at its up- `per end with two Separate tubes, one of Whichthecurved tube-N- dips into the oilchamber, while the other-the straighttube vNz-afords an outlet for steam into the condensing-chamber,substantially as described..

2. In a lubricator in which the lubricant is discharged by'water ofcondensation, an oil-` chamber provided with an outlet in its botv tom,a Valvefor closing said opening, provided With a valve-stem, the saidvalve and its stem 5'5 being located .wholly within the space inclosedby the outer Walls ofthelubnicatorfand the cap Oprovided'witha-wrenchadapted tobeappliedtothe `valve-stem vto turn' the same,substantially asdescribed.

rvated by turning` the body of the lubricator to ,open or close theopening through' the'tube' I, as set forth.

4. In a lubricator for ,steam engines,- in which the. lubricant isdischarged by the condensed steam, the oil-discharge pipe provided witha Wire cage for causing the oil to form in large drops, substantiallyasA andfor the MAURICE SPITZER.
